Application filed Juli 18, 1921. Serial No. 478,591.

Our invention consists in a conyertible washing machine comprising a mam sup.--'

' porting frame, driving motor and operating gearing combined with appropriate 'lIltBf- 5 changeable appurtenances whereby the power of the motor is available for washing either clothes or dishes as desired, each in a separate water tank with water circulation therethrough and without contact of dish water with clothes washing parts or vice versa. The invention includes means 01 draining away the dish water without contact with the clothes tank and also other features hereinafter made apparent, where-,

washing machines may be prac by existing tically converted and their utility extended to the. operation of washing dishes with the least possible additional expense.

Our invention lies in the dish washing mechanism as such as well as in the broad combination above described in which; the dish-washing attachment constitutes an element, and provides certain improvements in eludes water circulating devices, which in. the form illustrated, consists principally in an impeller having one or more blades, each formed witha plurality of angular surfaces,

and various of. its details having been omitted as irrelevant to 'the invention of this apf plieation. V

1,277 ,604, September 3, 1918, the Kirby construction being in some respects simplified tank and appurtenances of into positionoverthe 'and'the tank to be then supported by the connection, with the drive'aspindle of the washing machine, and

Fig. 4 is a, side elevation of the impeller. The washing machine includes a "main frame which may be'saidto comprise the clothes washing tank 1 having cylindrical side 'wall 2, fiat bottom 3, and central bearing sleeve 4, and the legs 6 connected by brace bars 7, 8. -The; tank 1 has afdrainoutlet 5 which is normally closed by suitable means when this tank is in use.

The vertical drive'spindle 9, journaled in the sleeve 4, is driven by the frame-supported motor 10 havinga friction drive disc '11 contacting with the rim of journaled on thesleeve and normally held yieldingly in contact with the disc. The friction wheel 12 hasa' pinion 13'meshing with gear 14 fast on a hub 15 of gear 16 loose on .stud 17 earried'by the. frame. The gear 16 meshes with a gear 18 whose hub 19v is splined to spindle 9 by a pin 20 arranged e spindle. When the machine is used for clothes washing a usual clothes container is placed on and secured to the spindle for rotating therewith as in the a-foresaid'Kirby patent.

The construction of this well known clothes washing machine will be recognized from the drawing so far as illustrated and its mode of operation will be understood by those skilled-in this art without description. By removing the thumb nut, the clothes conto engage a friction wheel 12 tainercan be lifted off the spindle and re- For the-conversion of the clothes washing machine into a dish washing' machine, We substitute for the removable clothes conta-iner, a dish washing tank and appurtenances which may be so related to the driving spindle as to receive from the latter such operation as may into a dish washing machine as shown in Fig.

be desirable or necessary, the washing; machine being thus converted 1, wherein appears the dish washing tank 22' having sidewall 23, conical bottom 24, and central vertical sleeve 25-adaptedto slide sleeve 4, which it fits,

annular flange 26 in whichjts side wall 23 terminates 'and which rests upon the edge of the cylindrical side wall2 of the outer receptacle 1, and by the junction of its sleeve with the conical bottom 24 which junction rests upon the bottom 3 of the outer receptacle.

In a convertible clothes washing and dish washing machine, it is essential to prevent dish water from coming into contact with clothes washing parts and this object is accomplished in the construction illustrated in part by the sleeve 25, in part by the flange 26, but especially by the dish water draining means which comprises the horizontal passage 27 leading from the dish washing tank 22 near its lowest part adjacent the center and having a downwardly extended plug-form nozzle 28 adapted to enteror register with the outlet 5 of the outer tank 1. This nozzle 28 is provided with a plunger valve 29 which controls'the opening and closing of a port 30 in the pasage 2? by movement toward and away from its seat 31 in the nozzle 28. For convenient manipulation of this valve its stem 32 is extended to a point adjacent the I top of the dish washing tank and is surrounded by a riser tube22 secured in and passing through the passage 27, furnishing the nozzle 28, the seat 31 for the valve 29, and the port 30, and extending up through the bottom of the dish washing tank to a point adjacent the upper end of the valve stem. A strut 34 connecting bottom 24 and passage 27 insures the requisite .strength and rigidity. This is a convenient way of preventing dish water from reaching the outer receptacle while permitting its drainage from the dish tank without removal of the latter.

The dish washing tank 22 is provided with a series 10f fixed bafi le plates 35 angularly disposed along the wall 23 and bottom 24,-

sothat their top edges are substantially parallel with the conical bottom and their ver tical edges substantially at right angles to the bottom 24:, thereby constituting obstructions to promote the outward passage of the liquid and forming pockets open at the top and inner side to the tank proper.

The dish washing devices are also provided with appurtenances whereby the water is caused to circulate among the dishes which are supported in any suitable way within the. dish washing tank. These means for causing circulation are removably securable to the driving shaft or spindle in lieu of the clothes container and in the construct-ion illustrated and which has various advantages, are as follows:

The agitator or impeller having the ver-' tical tubular shaft 36 closed at its upper end except for the squared hole 37 arranged to fit 24:, and in operation throwing water toward the baflie plates. As will be apparentythe blades are located between the baffie plates and the hollow shaft 36, which has its lower portion enlarged to accommodate the vertical sleeve 25 of the dish washing tank 22. Each blade is inclined to its direction of motion so that the lower edge will extend forwardly of the upper edge, the upper and lower edges of each blade being substantially parallel with the conical bottom 24 and the outer edge of the blades substantially parallel with the inner vertical edges of the baiiie plates. Each ofthe'blades 39 is corrugated forming a plurality of edges 40 and intervening channels 41, thereby presenting flat faces 42, 43 which are oppositely disposed. As the blades are rotated, by the rotary spindle 9, the liquid is forced upwardly and outwardly and caused to strike the battle plates, and is well broken up and splashed inwardly toward the tubular shaft 36, active circulation of water among the dishes being thus insured. The means for supporting the dishes consists of the basket 46 of wire or other suitable material formed with a conical bottom and provided with wire projections 47 for holding the dishes and other culinary utensils between them. Cleats 48 secured to the bottom of the basket rest upon the bafiie plates 35 and hold the basket with the articles to be cleaned therein in position to be splashed by the liqcoming into contact therewith. The basket is provided with handles 50.

The outer receptacle 1 has a removable cover 51having a depending rim 52 fitting snugly over the side wall 2 of the receptacle.

By reason of the effective circulation and dispersal of the liquid which is promoted by the particular construction of the agitator blades, the liquid will be caused to be splashed repeatedly upon the dishes with the least ex; penditnre of power. This agitation and circulation of the liquid is further promoted by the fact that the outer ends of the blades travel in close proximity to the substantially vertical inner edges of the battle plates, so that the body of liquid moved by the blades is forced by centrifugal action against the plates, the impact of which causes the liquid to be broken and forced upwardly and inwardly into and upon the dishes in the basket and thence to the bottom of the tank whence it is returned by the impeller to the dishes as before.

It is obvious that various changes may be resorted to in theform, construction and arrangement of the several parts without departing from the spirit and scope of our in vention, hence, we do not wish to belimited to the details herein shown and described'except as they may be specifically included in the claims.

What we claim is:

1. In a combined dish and clothes washing machine, the combination with a main tank and an operating motor, of a dish-washingtank removably insertable in said main tank, and dish-washing mechanism appurtenant to the dish-washing tank and connectable to said-motor for operation thereby;
